The use of corridors by Mammals in fragmented Australian eucalypt forests

Abstract

We used a replicated sampling program to examine the use of roadside corridors as habitat by native mammals. Our procedure compared the abundance and diversity of mammals in remnant forest, pasture, and two types of roadside corridor. Fixed transects were established in these four habitat types at six replicate sites. Spotlight, live-trap, and daytime observation surveys were used as census techniques. Few mammals were detected in pasture, and spotlighting revealed a higher total density of mammals in corridors than in forests, indicating corridors provide important habitat. Nevertheless, the number of species using corridors distant to forest was less than that in the corridors close to for..
